Description
Holley LT5 Angle Correcting Throttle Body Adapter
Precision CNC-machined billet aluminum wedge adapter engineered to correct throttle body angles and provide crucial clearance for GM Gen V LT5 installations.
Optimised Clearance & Alignment Solution
When swapping or fitting GM Gen V LT5 throttle bodies onto custom intake manifolds or performance engine builds, clearance against aftermarket accessory brackets, cooling hoses, and structural hardware is often severely restricted. The Holley 717-16 Throttle Body Angle Adapter resolves routing and fitment obstacles by angling the throttle body upward and towards the passenger side while maintaining high-volume airflow.
Crafted from premium black anodised billet aluminum with a 95mm main port inner diameter, this precision adapter ensures an exact seal via its integrated O-ring gasket and multi-bolt pattern compatibility for custom high-performance induction setups.
